acter of the fitting being such that in any of these positions easyaccessmay be had to the interior of the pipeline "for the cleaning thereof. V 11 I 3 Another object of the invention is to pro-- 'vide, in a manner as hereinafter set forth, a [cleanOut fitting having an 01f setportion nor- .mally closed by a plug-andhaving associated with the plug a stem designed to closethe off set portion so that the collection of sediment or grease in the off set will not occurto'any great extent. v t v, Still another object of the invention is to 'provide'a means whereby in a plug of this character any grease orsedimentwhichmay, have collected in the'o-fl' set referred to above 5 will be cleanly removedfrom the wall of the ofi setiportioncwhenthe plug is rotated for removal. 5 r The invention will be bestunderstood from a consideration of 'thefollowingl detailed description taken in connection with the ac- 1 companying drawing forming a partof this specification, with the understanding, however, that the invention is not confinedto any strict conformity with the showing; of the drawing but may be changed ormodified so long as such .changesor modifications mark nov materialdeparture from the salient features of the invention as expressed in the-,ap'

pended claims. 7

sponding parts throughout theseveral views, the "numeral 1 indicates as a whole the} fitting v embodying the present. invention, the same consisting as shown, of -a four-way' piece forming two passageways-2 and 3 arrangedin acute angular relation so that the angle between the adjacent ends' i is of approxlmately4;5.' I

Each of the open ends 4 of the fitting is in} ter iorly threaded andthere-isprovided with each fitting astandard plug-5 and a special ;type of plug indicated bythe numeral 6. c

The special'type of plug6 comprises a body? 1 having'a'polygonal shaped hea'd8'upon one end to facilitate the application of a wrench to the-plug and extending from the opposite U end is a stem 9, relatively long and fof'le'ss diameter than the plug.{ The stem 9 is pro? vided with a plurality of longitudin'allyiiex as'indi'cated at 11 andthe face 'isdep'ressed or dished so that when the plug 7 is fitted into one'oftheoutlets e, the stem 9 will termi-p nate with its curved face flush with the inner I face of thepassage extendingthereacrossi The application of the fitting is's'hownin Figure'l wherein the; fitting is s'how'n as forming' an elbow. b e'tween a pair of right angu larly'related' pipes 12 As isshown 'the out 9 "let end-0r arm of thefittingwhich'is inalign- 'ment with the horizontal one of the pipes 12 isclosed by the standard plug 5 whereas the outlet 'end-of the other arm of the "fitting is closed by the special plug 6. The stem 9 of the special plug'fills the end of the fitting arm in which; the plug islrpositioned-so' that this end of the arm is' prevented from trapping may flow through the pipes 1 As itais desirable that these special plugs be made of'brass'or'similar material it is necessary that'the stems be formed so that there will not be too close a relation between them and the body of the arm of the fitting in whichthe special plug is placed, therefore, a slight space'is leftbetween the stem and the wall of the fitting.
